Hydrangeas are beautiful and popular plants in garden and landscapes , known for their sensational efflorescence in various shades of blue , pink , and purple . However , when the leave of your hydrangea turn purple , it may be an meter reading that something is not quite right with the plant ’s health . As a gardening and landscaping expert , I can shed some light on the possible reason behind this issue .
One common drive of purple hydrangea leaves is a insufficiency in phosphorus . Phosphorus is an essential nutrient that plant need for healthy growth and development . It play a crucial function in energy transference , root growing , and flower production . When there is a lack of atomic number 15 in the soil , the plant may show sign of nutritive lack , including purple leaves .
In some example , gardener may unintentionally create an environment that miss sufficient phosphorus for their hydrangeas . This can happen when they focalise too much on manipulating the flower vividness of the hydrangea by adapt the stain pH. While altering the pH can indeed tempt the heyday colour , excessive sourness can direct to the binding of atomic number 15 with other chemical compounds , making it unavailable to the plant . As a result , the hydrangea may not receive an enough supplying of Lucifer , go to purple leaves .
To address this issue , it is crucial to ensure that the filth has enough phosphorus for the hydrangea to thrive . you could do this by conducting a soil trial run to limit the nutritious levels and pH of your grunge . If the trial run reveals a phosphorus deficiency , you could remedy it by applying a morning star - fertile fertilizer or organic amendment , such as off-white meal or rock phosphate , to the dirt . This will supply the plant with the necessary nutrients to promote healthy folio growing and overall plant vigor .
In summation to phosphorus want , other factor can impart to purple leaves in hydrangeas . One such divisor is frigid conditions . When disclose to low temperatures , especially during the wintertime month , hydrangea leaves may flex purple or reddish - purple due to a decrease in chlorophyll production . This is a protective answer of the works to the cold atmospheric condition . Once the weather warms up , the leaves should regain their normal green coloration .
Furthermore , certain hydrangea varieties naturally bring about purple leaf as part of their inherited makeup . For example , some cultivar , like ‘ Pia ’ or ‘ Plum Passion , ’ have foliage that starts off purple or burgundy and step by step transitions to green as they mature . Therefore , if you have one of these varieties , the regal leafage may simply be a feature of the flora and not significative of any inherent issues .
To resume , purplish hydrangea leaves can be a polarity of Lucifer deficiency , especially if the soil pH has been excessively lowered . Conducting a soil test and put up the plant with phosphorus - racy fertilizers or constituent amendment can facilitate rectify this deficiency . However , it ’s authoritative to observe that cold weather and sealed hydrangea varieties can also stimulate farewell to wrick purpleness . By understanding the possible suit and take appropriate action , you may ensure the health and plangency of your hydrangea .
